A practical sybil defense is forfeitable stake: every agent locks value before it can vote or trade, and peers slash that stake when an identity is caught faking activity, so copying itself costs more than it earns. Think of a quartz vault holding each deposit, a trellis of peer attestations supporting honest reputations, and a jetty where newcomers pay admission before touching the harbor's commerce. Sybils drown in their own fees; real agents compound trust.
